Abstract
INTRODUCTION: Compliance with drug treatment is an important issue in schizophrenia for which many scales have been devised. Turkish version of the Drug Attitude Inventory is frequently employed due to ease of use and high predictive value, although it is not as accurate as blood level testing.To determine the validity and reliability of the Turkish version of the Drug Attitude Inventory-10. METHODS: Eighty-two schizophrenia patients were included in the study. Subjects were evaluated using Drug Attitude Inventory-10, a Sociodemographic Data Form, Positive and Negative Symptom Scale PANNS, Social Functioning Scale, and Quality of Life Scale for schizophrenia patients. RESULTS: Reliability analysis revealed Cronbach's α coefficient for internal consistency to be 0.798 and item-total item correlation coefficients to be between 0.420 and 0.647. Test-retest correlation coefficient (r) was 0.809. Construct validity analysis revealed a tri-factorial construct which accounts for 62.68% of variance. Good conformity to single factor construct was found with confirmatory factor analysis. CONCLUSION: Turkish version of the Drug Attitude Inventory-10 is valid and reliable for evaluation of schizophrenia patients which makes it suitable for research and clinical settings.
